Introduction Let Gbe a complex simple algebraic group and let g be its Lie algebra. A nilpotent orbit O in g is an orbit of a nilpotent element of g by the adjoint action of G on g. Then O admits a natural
WebFor example, these orbits have a linear ordering with respect to the closure relation, and $ K_{\mathbb C} $ acts on them in multiplicity-free manner. We clarify the $ K_{\mathbb C} $ -module structure of the regular function ring of the closure of these nilpotent orbits in detail, and prove the normality. WebThe second chapter is devoted to nilpotent orbits, which is also a classical topic treated thoroughly in several textbooks. We insisted on two aspects of the theory. First, the geometric properties of nilpotent orbits and their closures: this includes the Kostant-Kirillov-Souriau form, the Springer resolution and its variants, the structure of
